See how art collective Greyworld created a spectacular sun which was raised over Trafalgar Square as part of Tropicana’s Brighter Mornings campaign.

Taking over six months to create, the Trafalgar Sun is 30,000 times bigger than a football, has a surface area of 200m2 and weighs over 2,500kgs. Its internal light source produces the equivalent of 60,000 lightbulbs, 4-million lumens of light.
